I'm planning to get an Ultra 5 245KF processor which has a TDP of around 150W. I'm considering whether to purchase an Arctic Liquid Freezer 360 AIO cooler for an additional 50 euros, or if I should stick with an air cooler like the AK-620. My case is a Lian Li Lancool 207, known for its great airflow according to various reviews. Is the AIO worth it?

I'd say no to paying extra for the AIO, even for pricier air coolers. Dual heat sink setups are pointless in well-ventilated cases.
For the best value, just find a tower cooler you like within your budget and go with that. If the visual appeal of an AIO attracts you, then consider it.
You should only consider the AIO for looks—it's really the only benefit these days. Air coolers are cheaper, quieter, and reliable enough to last through several builds. I've been using mine from a decade ago, and it still handles temps well even with my 9800X3D.
TechPowerUp's review shows that the Ultra 5 rarely uses more than 150 watts, with an average of 70-100 watts. Typically, a high-quality air cooler can handle up to 220 watts, making the AIO overkill. If you want an AIO for looks or slightly quieter operation, check out options like ID-Cooling for around $60.
From a performance standpoint, the AK-620 is more than enough to cool that CPU. Going for the AIO won't really boost your performance. Unless you're drawn to the aesthetic of the AIO, I'd stick with the air cooler.
Plus, accessing components like the GPU is easier with an AIO, and they're simpler to clean compared to a dual tower cooler.
If aesthetics matter to you, go for the AIO. If not, grab an air cooler. Performance on the AIO might be slightly better, but not enough for real-world use to justify the cost.
Honestly, I think AIOs just look cooler. But I've not seen significant improvements in cooling, and some reviews even say they're not the best option.
Honestly, for a 245KF, it's almost never worth it to get an AIO cooler.

The AIO does keep my 14600K cool while gaming at 5.4GHz without throttling.
